Question
I live in Dallas,  what is the better grass for plantain  on this area    (St Agustine, Bermuda)

thanks arturo

Answer
I cannot say which is better for you but I will try to list the important things about each.

Bermuda: A high quality grass often used on golf courses. It requires full sun, regular and frequent irrigation, fertilizer about once a month in the growing season and close mowing weekly. A reel mower does it best.

St. Augustine: A "coarse" grass which requires regular irrigation about every ten days if no rain. Fertilize about two times a year (three would be ideal). Mow at about 3" with a regular (rotary) mower.
